I didn't get that from Ang's version at all. There was no pretentiousness there. He just wanted to make a film more about the psychology of the character, and for the most part I think he got it right. AND the action in Ang's Hulk is superior to Lettierier's. I'd say that 20 minute fight against the army in the desert leading to San Franciso is still one of the best action scenes in a comic book movie.
His Hulk had an actual personality of himself. Even if he didn't have much dialogue. The part where he was jumping through the air with a kinda, peaceful child like look on his face. Where he landed at that lake in the desert and was looking at his reflection and the moss. And also the scenes where Banner was looking into the mirror and Hulk was looking back at him "Puny human". Showed that Hulk and Banner are distinct personalities, that the Hulk persona actually kinda resents the puny Banner. And it had genius lines like this.
"Even now I can feel it, buried somewhere deep inside, watching me, waiting... But you know what scares me the most? When I can't fight it anymore, when it takes over, when I totally lose control... I like it"
